The dreaded TWW.

I thought counting the days down until Christmas was bad when I was a child. This terrible, awful TWW definitely makes Christmas morning seem easy 😂. 7 dpo, one week to go. I ovulated on the 20th. I took a test yesterday (6 dpo) which was negative because my Clearblue and <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> have different info. Clearblue says I should have started my period yesterday. Glow says I will start my period on 11/3. My last period was 10/2 and lasted 7 days. Clearblue adjusts your calendar based on cycle length the previous month which was 24 days. Glow uses the same info even if your cycle pattern changes. No signs of AF. So when should I test again?
